# Model Card for Model ID

<!-- Provide a quick summary of what the model is/does. -->

## Code to create model
```py
import torch
from transformers import MimiConfig, MimiModel, AutoProcessor

model_id = 'kyutai/mimi'
config = MimiConfig.from_pretrained(
    model_id,
    intermediate_size=64,
    hidden_size=16,
    num_hidden_layers=2,
    num_key_value_heads=2,
    upsample_groups=16,
    num_filters=8,
    codebook_dim=8,
    vector_quantization_hidden_dimension=8,
    codebook_size=32,
)

# Create model and randomize all weights
model = MimiModel(config)

torch.manual_seed(0) # Set for reproducibility
for name, param in model.named_parameters():
    param.data = torch.randn_like(param)

processor = AutoProcessor.from_pretrained(model_id)
```

## ONNX conversion code
```py
import torch
import torch.nn as nn
from transformers import MimiModel

class MimiEncoder(nn.Module):
    def __init__(self, model):
        super(MimiEncoder, self).__init__()
        self.model = model

    def forward(self, input_values, padding_mask=None):
        return self.model.encode(input_values, padding_mask=padding_mask).audio_codes

class MimiDecoder(nn.Module):
    def __init__(self, model):
        super(MimiDecoder, self).__init__()
        self.model = model

    def forward(self, audio_codes, padding_mask=None):
        return self.model.decode(audio_codes, padding_mask=padding_mask).audio_values

model = MimiModel.from_pretrained("hf-internal-testing/tiny-random-MimiModel")
encoder = MimiEncoder(model)
decoder = MimiDecoder(model)

dummy_encoder_inputs = torch.randn((5, 1, 82500))
torch.onnx.export(
    encoder,
    dummy_encoder_inputs,
    "encoder_model.onnx",
    export_params=True,
    opset_version=14,
    do_constant_folding=True,
    input_names=['input_values'],
    output_names=['audio_codes'],
    dynamic_axes={
        'input_values': {0: 'batch_size', 1: 'num_channels', 2: 'sequence_length'},
        'audio_codes': {0: 'batch_size', 2: 'codes_length'},
    },
)

dummy_decoder_inputs = torch.randint(8, (4, model.config.num_quantizers, 91))
torch.onnx.export(
    decoder,
    dummy_decoder_inputs,
    "decoder_model.onnx",
    export_params=True,
    opset_version=14,
    do_constant_folding=True,
    input_names=['audio_codes'],
    output_names=['audio_values'],
    dynamic_axes={
        'audio_codes': {0: 'batch_size', 2: 'codes_length'},
        'audio_values': {0: 'batch_size', 1: 'num_channels', 2: 'sequence_length'},
    },
)
```
